Before CY2018: restatedCommerce's current system run over what utilities reported for a year before CY2018. The disclosure published for that year followed the old law, which required Commerce to assign fuel shares to unspecified power; this run keeps unspecified power as its own Market category, and Commerce's statewide totals for these years differ from the statutory reports.

Utilities consign part of their allowances to these auctions and must return the proceeds to customers; the rest they hold for compliance or bank.
Allocated to “Big Bend Elec Coop” on Ecology’s schedule, filed as consumer-owned utility. A utility cannot sell these allowances to another company: it uses them for compliance, banks them, transfers them to an eligible generator, or consigns them to a quarterly auction, and the proceeds must go back to customers.

WA · IEEE 1366EIA-861 Schedule 3 has two parts. Part B is for utilities that calculate SAIDI and SAIFI and determine major event days under IEEE 1366-2003 or IEEE 1366-2012; Part C is for any other method, where the utility also states how it defines a momentary interruption and whether inactive accounts count as customers. Figures from the two parts are not comparable and the atlas never pools them; utilities under Part C do not share one method either.Definition ↗
